.SH DESCRIPTION
.sp
.LP
The template validation functions offer a way to validate the configuration
data of an service instance against the appropriate template data. The
\fBscf_tmpl_validate_fmri()\fR function returns the full set of errors for the
specified instance, and those errors can be printed or explored directly.
.sp
.LP
By default, the validation is performed on the composed data from the running
snapshot of an instance. A different snapshot can be explicitly selected by
specifying a valid snapshot name rather than \fINULL\fR for the \fIsnapshot\fR
argument. If \fIflags\fR includes \fBSCF_TMPL_VALIDATE_FLAG_CURRENT\fR, the
\fIsnapshot\fR argument is ignored and the current configuration is used.
.sp
.LP
By default, these functions also explore template data defined by the service
or instance itself, the service's restarter, and global template data. See
\fBsmf_template\fR(7) for more information about this composition.
.sp
.LP
An instance FMRI is required, and FMRIs that specify other entities (for
example, services) are explicitly rejected.
.sp
.LP
The \fBscf_tmpl_validate_fmri()\fR function validates an instance FMRI against
the template data in the repository. As described above, when the
\fIsnapshot\fR argument is \fINULL\fR, the default running snapshot is used. If
\fBscf_tmpl_errors_t **\fR is non-null, the structure is allocated and returned
to the caller for further perusal or printing of the errors.
.sp
.LP
The \fBscf_tmpl_errors_destroy()\fR function destroys and frees the
\fBscf_tmpl_errors_t\fR and all of the \fBscf_tmpl_error_t\fR structures to
which it refers.
.sp
.LP
The \fBscf_tmpl_next_error()\fR function takes a pointer to a
\fBscf_tmpl_errors_t\fR structure previously returned by
\fBscf_tmpl_validate_fmri()\fR. On the first call, it returns a pointer to the
first \fBscf_tmpl_error_t\fR found during validation. On subsequent calls, the
next error is returned. To resume processing from the first error, the caller
can use \fBscf_tmpl_reset_errors()\fR.
.sp
.LP
The contents of an \fBscf_tmpl_error_t\fR are determined by its type. Types
added as additional validation checks are introduced. Based on the error type,
a set of fields can be retrieved from the error.

The \fBSCF_TERR_PROP_TYPE_MISMATCH\fR, \fBSCF_TERR_VALUE_OUT_OF_RANGE\fR and

\fBscf_tmpl_value_in_constraint\fR(3SCF).

The \fBscf_tmpl_error_type()\fR function retrieves the error type.
.sp
.LP
The \fBscf_tmpl_error_source_fmri()\fR function retrieves a string with the
FMRI of the source of the template that was violated. This string is freed by
\fBscf_tmpl_errors_destroy()\fR.
.sp
.LP
The \fBscf_tmpl_error_pg_tmpl()\fR function retrieves strings with the name and
type of the property group template that was violated. If the property group
name or type was implicitly wildcarded (see \fBsmf_template\fR(7)) in the
template, this function returns a string containing \fBSCF_TMPL_WILDCARD\fR
("*"). These strings are freed by \fBscf_tmpl_errors_destroy()\fR.
.sp
.LP
The \fBscf_tmpl_error_pg()\fR function retrieves strings with the name and type
of the property group that was violated. These strings are freed by
\fBscf_tmpl_errors_destroy()\fR.
.sp
.LP
The \fBscf_tmpl_error_prop_tmpl()\fR function retrieves strings with the name
and type of the property template that was violated. If the property type was
implicitly wildcarded (see \fBsmf_template\fR(7)) in the template, this
function returns a string containing \fBSCF_TMPL_WILDCARD\fR ("*"). These
strings are freed by \fBscf_tmpl_errors_destroy()\fR.
.sp
.LP
The \fBscf_tmpl_error_prop()\fR function retrieves strings with the name and
type of the property that was violated. These strings are freed by
\fBscf_tmpl_errors_destroy()\fR.
.sp
.LP
The \fBscf_tmpl_error_value()\fR function retrieves a string with the value
containing the error in \fIval\fR. This string are freed by
\fBscf_tmpl_errors_destroy()\fR.
.sp
.LP
The \fBscf_tmpl_strerror()\fR function takes an \fBscf_tmpl_error_t\fR
previously returned by \fBscf_tmpl_next_error()\fR and returns in \fIs\fR. If
flags includes \fBSCF_TMPL_STRERROR_HUMAN\fR, \fIs\fR is a human-readable,
localized description of the error. Otherwise, \fIs\fR is a one-line string
suitable for logfile output.
.SH RETURN VALUES
.sp
.LP
The \fBscf_tmpl_validate_fmri()\fR function returns 0 on successful completion
with no validation failures. It returns 1 if there are validation failures. It
returns -1 if there is an error validating the instance.
.sp
.LP
The \fBscf_tmpl_next_error()\fR function returns a pointer to the next
\fBscf_tmpl_error_t\fR. When none remain, it returns \fINULL\fR.
.sp

The \fBscf_tmpl_error_type()\fR, \fBscf_tmpl_error_source_fmri()\fR,
\fBscf_tmpl_error_pg_tmpl()\fR, \fBscf_tmpl_error_pg()\fR,
\fBscf_tmpl_error_prop_tmpl()\fR, \fBscf_tmpl_error_prop()\fR, and
\fBscf_tmpl_error_value()\fR functions return 0 on success and -1 on failure.
